4 Claims.

My invention relates to improvements in combined package weighing, wrapping and sealing devices, and the objects of this invention are as follows:

First: To provide a. practical device of simple construction combining the usually separately performed operations of weighing, wrapping and sealing of packages or containers in one selfcontained unit.

Second: To provide a. balanced weighing attachment with weight indicator and incorporate the same in the structure.

Third: To provide a package wrapping attachment intended to automatically wrap a covering or enclosure sheet of paper, regenerated cellulose, or other suitable material around the container and also incorporate the attachment in the structure.

Fourth: To finally provide a glue transferring attachment for the purpose of transferring glue upon the label or cover portion of the package, this attachment to be removably arranged and located in a suitably positioned depression in the structure.

Fifth: To make provisions in the arrangement of the device to permit either one of the weighing, wrapping or glue transferring attachments to be incorporated individually or in combination with any of 'the other attachments.

Sixth: To design and arrange all of the mechanical parts of the device in so eflicient and simple manner as to permit the production of the device at the lowest possible cost and in large quantities.

These and other objects I attain by the novel combination of various parts and elements fully described in this specification and illustrated in the accompanying drawings in which:

Figure 1 represents a plan view of the complete device.

Figure 2 represents a sectional view along lines 22 in Figure 1.

Figure 6 is an enlarged view, in section, of the wrapping attachment in action.

Figure '7 is another enlarged sectional view showing the glue transfer attachment in action.

In the preparation of produce and similar products for distribution it is common practice to segregate the operations of weighing, packing, wrapping and sealing of the containers or boxes. This method is a rather cumbersome time consuming and requires a number of operators for the various stages of operation. To overcome these difliculties I propose to combine all sectional view along of the individual operating processes in one unitary structure the preferred form of which is illustrated in Figures 1 and 2. Upon a conveniently shaped common supporting base member 10, the weighing attachment 11, the wrapping attachment 12 and the glue transferring attachment 14 are suitably arranged and positioned.

The weighing attachment comprises a weighing platform 11a from which a pair of side arms 11b extend downwardly. A pair of parallel balancing arms 11c pivotally connect to side arms 110 at one end, while the other ends are also pivotally connected to a pair of balance weights 11d. Mounted on top of one of the balance weights a weight indicator shield lle is provided and made visible through a window 100 provided in a projecting pocket 10b, forming a part of base member 10. Parallel arms 11c freely move upon a. pair of shafts 11y, mounted in base member 10.

The, preferably centrally positioned, wrapping attachment 12 is located within a, for this purpose provided, perforation in base member 10, and comprises a four sided pocket like enclosure whose side walls 12a and 12b are securedly fastened to a stationary bottom plate 120. The top portions of the side walls terminate into, spring actuated, hinged wings 12d and 12e, as shown in Figures 1, 4 and 6. These wings are held in their normally upright position by a movable platform 12 pushed upwardly by two pairs of spring actuated levers 12h, pivotally mounted upon shafts 129.

In Figures 1, 3 and 7 the glue transferring attachment 14 is illustrated. This attachment is removably arranged and located within a suitably shaped depression provided in base member 10 and comprises the glue container 14a, the also removable bracket 140, set into the glue container, the movable platform 14b loosely but securely joined to bracket 14c by means of headed pins 14h and two pairs of oppositely positioned pivoted operating and glue transferring levers 1411. Upon an excentrically positioned extension members 14c, forming a part of levers 14d, the movable platform 14a is loosely resting, while a pair of U shaped glue transferring bars 14f fasten to the other end of levers 14d. Levers 14d and bars 14) are, normally, immersed in the liquid glueing substance 15 provided in container 14a.

The complete device functions and is operated as follows: First the substance or material to be packed and sealed is laid upon the platform 11a of the scale, which being substantially horizontal will hold most materials. However, if the material is of such nature that it will roll on the platform, it can then be placed in a'suitable carton or container forming a part of the ultimate package. The weight indicator He will rise to the level of indicating line 16, see Figure 5, when the correct quantityis reached. Inasmuch as the functions of a balancing scale are well known no further explanation will be necessary.

If the product to be wrapped is not to be provided with a separate container, the goods are placed directly upon the platform 12f of the wrapping attachment, but if the goods are first placed in a container or carton then the carton is transferred from the scale to the platform of the wrapping attachment. A sheet of Cellophane or wrapping paper misplaced between the container 17 or the bulk material, as the case may be and platform 12 Container 1'! being filled and closed is now pushed downwardly against spring levers 12h till wing members 12d and 12e, by action of spring members 12f, fold over the edges of the box or container. With this operation the, for this purpose, properly shaped wrapping material 18 is folded up and over the sides of the container 17 and will,,due to the sharp bends at the corners, stay in position when the pressure upon the container is released and brought up to its surface position. Wing members 12d and 12e are forced back in their normal upright position ready for the following operation.

At this stage the label or covering sheet 19 is to be glued upon the folded over portion of the wrapper. Glue is transferred to the cover sheet by means of the glue transfer attachment 14. Cover sheet 19 is for this purpose placed upon platform 141), see Figure 7, and properly located by stop plate 20.

Now with sheet 19 in proper position, platform 14!) is pushed downward against extension members 14c, which by this action spread apart and cause levers 14d and the glue transferring bars 14f to move upwardly till bars 141 strike sheet 19 thereby taking portions of glue along and depositing the same upon sheet 19. Platform 14b and levers 14d resume their normal position when pressure is relieved and are again ready for action. The thus prepared cover sheet 19 is removed and placed upon the wrapped container 17 thereby completing the operations.

It may be observed that the weighing attachment can be easily detached by removing the shafts 11g and platform 11a. The same applies to the wrapping attachment, which by removing the mounting screws 12k, see Figure 4, can be completely detached.

The glue transferring device, presenting a self contained unit in itself, can be readily lifted out of the depression or pocket provided in base member 10. The platform structure 14b with the supporting bracket is also detachably arranged, being held in position by means of a pair of prongs 14g forming a part of container 1 a.

These features of the glue transferring device are of utmost importance as the cleaning and refilling of the device is not only greatly facilitated but the operations can be performed conveniently and remotely from the base member 10.

For many applications and purposes it will be found desirable to utilize only part of the various attachments, so for instance the weighing featurelcould be omitted or the wrapping attach ment may not be required, or either one of these features may be utilized singly or collectively with the glue transferring device and for this reason the removability of the attachments is obvious.

Having thus fully described and illustrated my invention I do not wish to confine myself to the exact details of construction and arrangement of the various attachments as disclosed, it being apparent that there may be many variations and considerable modifications of the individual members possible without departing from the spirit of my invention.

What I claim as new and Letters Patent is:
